Title
(EN) LUBRICANT SUPPORTED ELECTRIC MOTOR WITH A PROFILED RACEWAY
(FR) MOTEUR ÉLECTRIQUE SUPPORTÉ PAR LUBRIFIANT AVEC CHEMIN DE ROULEMENT PROFILÉ
Abstract
(EN)
A lubricant supported electric motor includes a stator presenting an outer raceway and a rotor extending along an axis and rotatably disposed within the stator to present an inner raceway disposed in spaced relationship with said the raceway to define a gap therebetween. A lubricant is disposed in the gap for supporting the rotor within the stator. At least one of the outer raceway or the inner raceway are profiled with a non-circular, cross-sectional shape for maintaining consistent support of the rotor over a wide range of operating speeds and dynamic situations encountered by the lubricant supported electric motor during operation.
(FR)
L'invention concerne un moteur électrique supporté par lubrifiant comprenant un stator présentant un chemin de roulement externe et un rotor s'étendant le long d'un axe, disposé de façon rotative à l'intérieur du stator et présentant un chemin de roulement interne disposé en relation espacée avec ledit chemin de roulement externe pour former un espace entre eux. Le lubrifiant est disposé dans l'espace pour supporter le rotor à l'intérieur du stator. Au moins un parmi le chemin de roulement externe et le chemin de roulement interne sont profilés avec une forme de section transversale non circulaire pour maintenir un support constant du rotor sur une large plage de vitesses de fonctionnement et de situations dynamiques rencontrées par le moteur électrique supporté par lubrifiant pendant le fonctionnement.
